- Recent European Society of Cardiology and American Heart Association/American College of Cardiology Guidelines did not recommend biomarker-guided therapy in the management of heart failure (HF) patients. Combination of echo- and B-type natriuretic peptide (BNP) may be an alternative approach in guiding ambulatory HF management. Our aim was to determine whether a therapy guided by echo markers of left ventricular filling pressure (LVFP), lung ultrasound (LUS) assessment of B-lines, and BNP improves outcomes of HF patients. Consecutive outpatients with LV ejection fraction (EF) <= 50% have been prospectively enrolled. In Group I (n=224), follow-up was guided by echo and BNP with the goal of achieving E-wave deceleration time (EDT) >= 150 ms, tissue Doppler index E/e' < 13, B-line numbers < 15, and BNP <= 125 pg/ml or decrease > 30%; in Group II (n=293), follow-up was clinically guided, while the remaining 277 patients (Group III) did not receive any dedicated follow-up. At 60 months, survival was 88% in Group I compared to 75% in Group II and 54% in Group III (chi(2) 53.5; p<0.0001). Survival curves exhibited statistically significant differences using Mantel-Cox analysis. The number needed to treat to spare one death was 7.9 (Group I versus Group II) and 3.8 (Group I versus Group III). At multivariate Cox regression analyses, major predictors of all-cause mortality were follow-up E/e' (HR: 1.05; p=0.0038) and BNP > 125 pg/ml or decrease <= 30% (HR: 4.90; p=0.0054), while BNP > 125 pg/ml or decrease <= 30% and B-line numbers >= 15 were associated with the combined end point of death and HF hospitalization. Evidence-based HF treatment guided by serum biomarkers and ultrasound with the goal of reducing elevated BNP and LVFP, and resolving pulmonary congestion was associated with better clinical outcomes and can be valuable in guiding ambulatory HF management.

- Aims. The Cardiac Resynchronization Therapy (CRT) Survey II was conducted between October 2015 and December 2016 and included data from 11088 CRT implantations from 42 countries. The survey’s aim was to report on current European CRT practice. The aim of this study was to compare the Croatian national CRT practice with the European data. Methods. Five centres from Croatia recruited consecutive patients, in a 15-month period, who underwent CRT implantation, primary or an upgrade. Data were collected prospectively by using online database. Results. A total of 115 patients were included in Croatia, which is 33.2% of all CRT implants in Croatia during the study period (total n=346). Median age of the study population was 67 (61–73) years, and 21.2% were women. Primary heart failure (HF) aetiology was nonischemic in 61.1% of patients, and HF with wide QRS was the most common indication for the implantation (73.5%). 80% of patients had complete left bundle branch block, and over two-third had QRS ≥150 ms. Device-related adverse events were recorded in 4.3% of patients. When compared with European countries, Croatian patients were significantly younger (67 vs. 70 years, p=0.012), had similar rate of comorbidities with the exception of higher prevalence of hypertension. Croatian patients significantly more often received CRT-pacemaker when compared with European population (58.3 vs. 29.9%, OR 3.27, 95%CI 2.25–4.74, p<0.001). Conclusion. Our data indicate strict selection of patients among HF population and adherence to guidelines with exception of higher proportion of CRT-pacemaker implantation. This is likely to be influenced by healthcare organization and reimbursement issues in Croatia.

- Introduction. The wide variety of symptoms in patients with cardiac arrhythmias can affect daily living activities. The evaluation of symptoms with patient-reported outcome measures (PROMs), with validated instruments, can provide information that contributes to clinical decisions and treatment. In Brazil, however, there is no available scale that evaluates symptoms in different types of arrhythmias. Purpose. This study aimed to translate the Arrhythmia-Specific Questionnaire in Tachycardia and Arrhythmia symptom scale (ASTA-symptom scale) and then validate the questionnaire in terms of Brazilian culture. Method. The methodological process of cultural adaptation used was based on international literature guidelines consisting of forward translation, synthesis, back translation, review by an expert committee, and pretest. Psychometric analyses were conducted with 140 patients. These included measuring internal consistency (Cronbachs alpha), construct validity with item-total correlations, and convergent construct validity with correlations with the quality of life questionnaire for patients with atrial fibrillation-version 2 (QVFA-v2). Usability and understandability were evaluated through the usability evaluation of instruments. Results. The translation and adaptation processes were performed by obtaining the Brazilian Portuguese version of the original Swedish instrument. This version presented the internal consistency of items, evaluated through Cronbachs alpha (0.79). Construct validity was demonstrated by item-total correlations for the nine items, all except one reached the level of >0.30 (0.24). Convergent validity showed a high correlation with QVFA-v2 (0.89). As for the evaluation of usability and understanding, after two small suggested changes, no additional alterations were necessary. Conclusion. The psychometric properties of the Brazilian version of ASTA-symptom scale evaluated in this study were satisfactory, and the scale was proved to be a valid and reliable tool to assess the symptom burden in patients with different forms of tachyarrhythmia. The ASTA-Br-symptom scale questionnaire can be an important addition to PROMs for patients with arrhythmias and could help healthcare professionals in decision-making.

- Physicians caring for the critically ill are now expected to acquire competence in echocardiography. It has become an indispensable diagnostic and monitoring tool in acute care settings where it is generally accepted to have therapeutic impact. There are a number of indications for a critical care echocardiographic study, and the most important queries include those pertaining left and right ventricular function and filling status. Focused examinations are increasing in popularity and provide a means for systematic study, and can be easily learned and practiced by novices. This paper addresses the indications, therapeutic impact, and some of the most common questions that can be answered using echocardiography the in critically ill patient.

- The hypertrophic cardiomyopathy (HCM) disease process is not only limited to cardiomyocyte abnormalities but also engages the extracellular matrix. Hyaluronan (HA) and its receptor CD44 are involved in cellular growth and tissue proliferation but have so far been less studied in myocardial hypertrophy. In HCM, collagens are abundant but their histological distribution and relation to hyaluronan have not been described. Material and Methods. Myocardial specimens from 5 patients with symptomatic left ventricular tract obstruction undergoing myectomy due to HCM were processed for histochemistry and immunohistochemistry. Results. HA staining was more intense in HCM patients. The histological distribution of HA was the same in patients and controls, that is, interstitial staining including the space between cardiomyocytes, in fibrous septa, and in the adventitia of intramyocardial blood vessels. CD44 was not detected in the myocardium of patients or controls. Collagen I showed the same general localisation as HA but detailed distribution differed. Conclusions. This is the first study that describes the distribution of hyaluronan in human HCM. HA staining is more intense in HCM patients but without coexpression of its receptor CD44, at least not in the chronic phase of HCM. HA and collagen I have the same localisation.

- Introduction. Awareness of epidemiological and clinical consequences of atrial fibrillation (AF) has increased, as have disease-related costs. Less attention has been paid to patient-related issues, such as understanding how symptoms, different therapies, and lifestyle adjustments affect daily life. We aimed to describe patients experiences of living with AF. Methods. The study design used a parallel convergent mixed methods approach. Patients with AF were included in the SMURF study and referred for catheter ablation. Patients completed questionnaires on symptoms, health-related quality of life, depression, anxiety, and perceived control and were interviewed. The datasets were analysed separately using inductive content analysis and descriptive statistics. Data were merged to obtain a final interpretation. Results. Nineteen patients were interviewed and 18 completed questionnaires. Twelve of the patients were male, mean age 60 years (45-75 years). Inductive qualitative analysis revealed three categories: (i) symptoms and concerns limiting life, (ii) dimensions of worries, and (iii) strategies for management. The most common symptoms were tiredness, weakness/fatigue, and breathlessness during activities, and the most pronounced negative impacts on health-related quality of life (HRQOL) were physically related, shown in the ASTA questionnaire. The most negative SF-36 scores were found in role limitations due to physical health problems and vitality. HADS revealed five patients with some degree of anxiety and four with some degree of depression. Patients had lower scores on perceived control than perceived helplessness in CAS. Patients perceived control was higher than their families, and families experienced more helplessness. Conclusions. The mixed methods design deepens our understanding of challenges faced by patients. Patients experienced a limited ability to perform activities of daily living due to AF which created different kinds of worries that encouraged the use of various strategies to manage their lives. Healthcare providers need to be aware that relationships between patients and their relatives can change, and therefore they need to be supported and integrated into the care system.

- Objective. To examine the changes in health-related quality of life (HRQoL) in patients with coronary artery disease (CAD) in terms of age, gender, and treatment strategy in Iran. Methods and Materials. Forty-nine patients responded to the Iranian version of the 36-item short form (SF-36) questionnaire to evaluate the HRQoL at first and third year after treatment. The paired and independentWilcoxon rank-sum tests were used for within and between comparisons, respectively.Multivariate regression analysis was used to analyze the predictors of changes at HRQoL. Results. In general, during followup, the mental component summary scale improved, and the physical component summary scale declined. The results of multiple regression showed that the score at the first year post-treatment was the main predictor of HRQoL at follow up. Moreover, after adjusting for other covariates, receiving PTCA and being at older age were related to lower scores at followup, but these were not statistically significant in most cases. Conclusion. The HRQoL significantly changed from one to three years after treatment in patients with CAD. While, the physical health deteriorated during two-year follow up, mental health improved at the same time period. Generally, there were no significant differences at changes of HRQoL in terms of treatment, age, and gender.

Tidskriftsartikel (refereegranskat)abstract
- Using a fluid-filled wire with a pressure sensor outside the patient compared to a conventional pressure wire may avoid the systematic error introduced by the hydrostatic pressure within the coronary circulation.To assess the safety and effectiveness of the novel fluid-filled wire, Wirecath (Cavis Technologies, Uppsala, Sweden), as well as its ability to avoid the hydrostatic pressure error.The Wirecath pressure wire was used in 45 eligible patients who underwent invasive coronary angiography and had a clinical indication for invasive coronary pressure measurement at Sahlgrenska University Hospital, Gothenburg, Sweden. In 29 patients, a simultaneous measurement was performed with a conventional coronary pressure wire (PressureWire X, Abbott Medical, Plymouth, MN, USA), and in 19 patients, the vertical height difference between the tip of the guide catheter and the wire measure point was measured in a 90-degree lateral angiographic projection. No adverse events caused by the pressure wires were reported. The mean Pd/Pa and mean FFR using the fluid-filled wire and the sensor-tipped wire differed significantly; however, after correcting for the hydrostatic effect, the sensor-tipped wire pressure correlated well with the fluid-filled wire pressure (R=0.74 vs. R=0.89 at rest and R=0.89 vs. R=0.98 at hyperemia).Hydrostatic errors in physiologic measurements can be avoided by using the fluid-filled Wirecath wire, which was safe to use in the present study. This trial is registered with NCT04776577 and NCT04802681.
